New Low‑Waste Process Turns Tough Vehicle Plastics into Reusable Material

A new recycling technique promises to address one of the most stubborn problems in plastic waste management: the efficient breakdown of high‑density, cross‑linked polymers that resist conventional mechanical recycling. The method, developed by researchers at the Institute for Advanced Materials, employs a mild, catalyst‑free enzymatic process that selectively cleaves the long carbon chains in polyethylene terephthalate (PET) and polycarbonate, producing monomers that can be repolymerized without generating significant by‑products.

Unlike thermal or solvent‑based approaches that often produce toxic residues or require high energy inputs, the enzymatic route operates at ambient temperatures and uses only water and naturally occurring enzymes. Early laboratory trials have shown a 90 % conversion rate for PET bottles and a 75 % yield for polycarbonate electronics casings, while the waste stream consists mainly of harmless aqueous solutions. If scaled, the technology could reduce landfill volumes and lower the carbon footprint associated with plastic disposal, offering a more sustainable alternative for industries that currently struggle to recycle these durable materials.

While the technique is still in the pilot phase, the researchers are collaborating with several manufacturers to test the process on a commercial scale. If successful, it could become a key component of circular economy strategies, helping to close the loop on plastics that have long been considered a persistent environmental hazard.
